Everyone who visits Lucknow must have gone to Bara Imambara and has seen the mystic bhulbhulaiya. I had a visit at childhood. My the then memory reminds me of a place where people can get lost if not properly guided. I can recall a moment when our guide left us in a place and told that within ten minutes if we could get ourselves out of the bhulbhulaiya, he would not accept his charge. We failed miserably to get out of the place. We tried for half an hour. Everytime it seemd that we were landing at a same place. After we surrendered to him(the guide) he took only few seconds to show us the stairs to get outside.
Rule of reverse : Last June, I again had an opportunuty to visit Bhulbhulaiya after 20 years. I was expecting for the offer from the guide. But he did not turn up. So I by myself told him (after he showed guided us) that we would be trying to get out without his help. He told that we would not be successfull. For first five minutes my experience was same as I had twenty years ago. Suddenly something clicked in my mind. I made a rule of reverse. If someone needs to climb up he need to take to downwards step. Same is thing to go down. going to left and right also had the same method. I wondered that the rule clicked. We were being able to move wherever we were wanting. Then it was a matter of few minutes we were at outside without the help of guide. Amazing and wonderful piece of art ! Is not it ? < I am referring to the planning and structure of bhulbhulaiya>.
So many years ago someone designed this marvel, I am sure many experienced enginner of todays modern era armed with sophisticated automated designing software will never get any clue in their dream also to how to build a structure like this.
